10 Facts about Sunscreen You May Not Already Know
1. While UVB rays cannot penetrate glass windows, UVA rays can. The American Academy of Dermatology (AAD) recommends that even when indoors, you should apply a light SPF on areas of skin that are exposed such as hands and face.
2. Sand reflects 25% of the Sunâs rays; snow reflects 80% of the Sunâs rays.
3. Most people apply only 25-50% of the recommended amount of sunscreen. (One ounceâenough to fill a shot glassâis estimated to be the right amount to cover exposed areas of the body properly).
4. Just as regular sunscreen must be reapplied throughout the day for continued UV protection, lotions and creams with SPF in them must also be reapplied to stay effective.
5. The right ingredients to look for on a bottle of sunscreen include avobenzone (Parsol 1789), cinoxate, ecamsule (Mexoryl SX), menthyl anthranilate, octyl methoxycinnamate, octyl salicylate, oxybenzone, sulisobenzone, titanium dioxide, and zinc oxide. Make sure it's a broad spectrum sunscreen that's over SPF 15 (preferably) water-resistant.
6. To know if a sunscreen product has been recommended by dermatologists, look for the AAD SEAL OF RECOGNITION on the bottle.
7. Sunscreens stay at their original strength for about 3 years. (But you should go through a bottle of sunscreen fairly quickly if you're applying the right amount.)
8. The number of SPF on sunscreens only reflects the productâs screening ability for UVB rays; there is currently no FDA-approved rating system that identifies UVA protection, but scientists are trying to come up with a way to measure this.
9. Wearing sunscreen will decrease Vitamin D production, but not enough to be a real issue except in those who are extremely deficient in the vitamin. Make sure your diet and/or vitamin regimine includes a sufficient amount of Vitamin D and youâll be fine. (The recommended daily allowance of Vitamin D in the U.S. is 200 IU per day and 400 IU per day for older people and those who donât get much sun exposure.)
10.THERE IS NO SAFE WAY TO TAN. (Except self-tanner products/spray tanning of course).
Sun screen as much as you hate to put it on is a must have! As you probably saw about two weeks ago I failed to do this and got extremely burnt, which was really unpleasant! But sure to apply whenever you are out in the sun! Here are some tips for being in the sun!
